Pretty Little LiarsSeason 3 has had more than a few crazy moments -- and the rest of 3B promises to be even crazier -- but that doesn’t mean the actresses are always stressed out on set … Well, at least not because of the show.In an adorable Pretty Little Liars featurette (via ET) Troian Bellisario (Spencer) and Shay Mitchell (Emily) give fans the behind-the-scenes scoop into what was really going when they filmed Season 3, Episode 16, Misery Loves Company. In the scene, the Liars come to Aria’s aide when she’s sick with the flu -- and stuck with Meredith. But while Shay calls the scene “comfortable” to film, Troian recalls it as anything but. In fact, she was in the middle of a full-blown panic attack!It looks like simultaneously planning a birthday party for your brother and a birthday party for your boyfriend in between takes isn't the most relaxing activity. Meanwhile for Shay, her only on-set drama involved a mug of very hot tea. But once those cameras do start rolling, their personal drama takes a backseat to their characters’ fictional drama, as we’ll see in tomorrow night’s episode. For now, watch Troian and Shay dish about the episode below. Catch the next episode of Pretty Little Liars on Tuesday, January 22, 2013 at 8 p.m. ET/PT on ABC Family.Source: ET Online
